Survey: assessing the quality of pitch shifting schemes in singing voice

(with apologies for cross-posting)

Dear colleagues,

We are conducting an online survey in order to evaluate the quality of
different pitch-shifting schemes, and we'd really appreciate your
participation, which only will take 5-10 minutes to complete.

The aim of this survey is to comparatively evaluate the quality of three
different pitch shifting schemes for singing voice. For this evaluation, we
have applied the three pitch shifting algorithms to several actual sung
notes. Each participant is asked to evaluate from 0 to 100 the quality of
the three transformations presented for each note regarding naturalness,
vowel intelligibility and breathiness.

Here is the link to the survey:


Thanks in advance for your participation!!
